When a postman is found dead at the bottom of his apartment stairs, his death appears to be a simple accident, and the perfect case for Detective Chief Superintendent Konrad Simonsen to return to after a severe heart attack. But new forensic evidence comes to light and something doesn't add up. Then life-size images of a girl are discovered plastering the walls of the dead man's attic. Who is she? Could she be alive? As the homicide team delves into the past, Simonsen discovers long-hidden skeletons in his own closet.
